cSetting switch SW2-1 to OFF configures the modem for high- speed (Fast Poll) mode. In this mode, the switches correspond to the functions in Table 2-1 (see page 13).

cSetting switch SW2-1 to ON configures the modem for low-speed (FSK) mode. In this mode, the switches correspond to the functions in Table 2-3 (see page 18).

Note: The modem has several jumpers. Do not change or remove the straps from the jumpers.
